Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655528, here are decompositions:

31 + 8655497 = 8655528
71 + 8655457 = 8655528
107 + 8655421 = 8655528
127 + 8655401 = 8655528
157 + 8655371 = 8655528
179 + 8655349 = 8655528
197 + 8655331 = 8655528
241 + 8655287 = 8655528

Showing the first eight; more decompositions exist.
